While we were fishing in Corpus Christi Bay and Aransas Bay last month, we caught a ton of what our captain called "hard heads". These looked like ordinary ol' channel cat to me. I started to take my first one off the hood when he freaked out and yelled don't touch him! He would only handle them with pliers, and killed every one of them that we would catch, all the while cursing them. My question is this, are they different from Channel Cat? I did grab a few of them and took them off the hook myself, just like a normal channel cat, and they left a considerable slime on my hand and my line, but I could not tell any other difference. He said you can't eat them, and nothing else would eat them so they were no good fot bait. Said they were nothing more than "trash fish" What is the deal? Is there a difference?
